Preheating Plate T-8120
1 / 6

Products Features:

1.The machine selects the infrared highly effective component to give off heat which independent exploration, adopt advanced PID intelligent controlling warm heating technology,
controls warm precisely.

2. Can achieve to heat PCB board and component which contains lead or not,suit for BGA/SMD.

3. Use infrared heat, easy to cut through, heat proportion, don’t have sirocco flow. Don’t
shift the small component on the PCB board,ensure the welding quality.

4. This machine has 600W heating system, widely to 120x120mm.Can use with the handhold infrared welder T-835.

5. Easily operate, can operate it through easy training.

Operation instructions:

1. Starting and inspects before starting:

①Check the temperature sensor and the power line.

②Turn on the power line. Don’t use until passing check. (The nixie tube displays the indoor temperature.)

③The black switch on the front panel use to control the infrared preheating chassis; press “▲”up,“▼”down,
can be at 0-450℃,adjust the infrared preheating chassis’s temperature. Press the button“WARM”,the infrared 
preheating chassis starts to work, press“COOL”,it stops working.

2.Operation of preheating PCB board:

(1) PCB board’s placement and adjustment:

①According to the PCB board’s size, adjust the location of the board support, put the PCB board on the support 
and fix the screw tightly with hands. Make the temperature measurement head fixed on the PCB board which 
needs to preheating, use aluminum-foil paper or adhesive paper to stick tightly.

②According to the size of PCB board and welding technological requirement, press “▲”and “▼”button, between 
0℃ and 450℃, regulate the output temperature of preheating chassis.

(2) Preheating opening and closure:

①Press the “WARM” button,open the preheating chassis about 3-5 minutes, make the temperature be about 
the setting value then carry on the step operation.

②After finishing,press “COOL”, the preheating chassis stop working.

Attention:This time can’ t close the power switch, after the machine full cooling then close the power source.

③General preheating temperature establishment suggestion: when PCB board has lead ,may adjust the 
infrared preheating chassis temperature to 100-120℃ ; When PCB board has non-lead, may adjust  to 120-
140℃ ; Also may set the different preheating temperature voluntarily according to user's use craft and experience.


1. After finishing, don’t turn off the power immediately; make the infrared preheating chassis full cooling.

2. Keep the ventilation free-flowing, the infrared preheating chassis pure; use the dehydrated alcohol to be clean regularly!

3. Careful, the high temperature operation, pay attention, avoids scalding.

4. Long-time doesn’t use, should cramp out the power source plug!

Guarantee acceptance

The complete machine maintains for one year and lifelong service. Long-term factory price supply .Provides the 
immediate network online Q/A and the technical advisory work service.
